* Funny thing: I can not re-produce it in a simple MCVE. I have found out the following for my UART example code

1. Debug image with hw mul: Works
2. Debug image with 32bit mul: Becomes stuck in weird loop, jumps back to previous code in main when stepping through UART clock calculations
3. Release image: Both work

So maybe this is just some bug related to running out of RAM, and not the HW mult support at all? the debug apps are sketchy anyway. I had to use optimization level 1 at the very least, or the RAM would overflow and I can not even compile a really simple app. I am really curious what takes up so much RAM space, so I will probably dig a bit more here..
